Error: java.lang.RuntimeException: Widget disposed too early

Troubleshooting


Problem

This technote explains how to resolve a java runtime exception error, "Widget disposed too early", that might occur when using IBM® Rational® ClearQuest® in a Linux® environment.

Symptom


After installing ClearQuest, the ClearQuest Eclipse Client (RCP) will not start. In the ClearQuest installation.log file you might find the following error:

!ENTRY org.eclipse.ui.workbench 4 0 2007-03-27 14:39:07.61
!MESSAGE Widget disposed too early!
!STACK 0
java.lang.RuntimeException: Widget disposed too early!


Similarly, ClearQuest may start but then the splash screen errors out referring to a log file that has the widget error above and the following SWTError:

!ENTRY org.eclipse.osgi 2008-04-25 14:29:19.298
!MESSAGE Application error
!STACK 1
org.eclipse.swt.SWTError: No more handles [gtk_init_check() failed]
at org.eclipse.swt.SWT.error

Cause


The root cause is that the Standard Widget Toolkit (SWT) runtime can not find or initialize the installed browser.

Note: This can also occur if there are problems with the version of xulrunner installed. For example, if you have mozilla-xulrunner on SUSE Linux, running an rpm -e command against the package might resolve the problem. For more information on this, see techote 1394977.

Resolving The Problem

The SWT FAQ offers a solution to resolve this issue. Notice the section specifically about a bug with IBM 1.4 VMs that may keep the necessary libraries of the LD_LIBRARY_PATH environment variable. The following section is copied from the SWT FAQ:

Q: How can I get the SWT Browser to work with the IBM 1.4 VM?

A: The IBM 1.4 VM accidentally removes certain entries of the environment variable LD_LIBRARY_PATH. This occurs in particular for entries starting with /usr/lib. It will leave untouched entries such as /usr/../usr/lib.

Instructions for Red Hat Enterprise Linux 3 users:

  1. Mozilla is installed in /usr/lib/mozilla-1.x on this platform. Set the environment variable MOZILLA_FIVE_HOME to /usr/../usr/lib/mozilla-1.x. The variable may also be set to the Firefox install directory if that is the browser installed.
  2. Start Eclipse. If you are not using Eclipse, add MOZILLA_FIVE_HOME to LD_LIBRARY_PATH before starting your standalone SWT application.
  3. The Browser widget should now work with the IBM VM.

Note: These instructions are for RHEL 4 and 5 as well.

This was logged as a documentation defect under APAR PK65929. The ClearQuest Information Center includes these necessary instructions starting in version 7.1.
